the technician is completely familiar with the equip-

ment and all its detail. It is recommended good practice 

that all refrigerants are recovered safely. Prior to the 

task being carried out, an oil and refrigerant sample 

shall be taken in case analysis is required prior to re-use 

of reclaimed refrigerant. It is essential that electrical 

power is available before the task is commenced.

of  the system. f ) Make sure that cylinder is situated 

on the scales before recovery takes place.    g) Start 

the recovery machine and operate in accordance with 

manufacturer’s instructions. h) Do not overfill cylinders.
